Flotation for wine clarification – how does it work and why use it?

Greg Howell and Carly Gamble, Vintessential Laboratories - 14 Sep 2017

Flotation, as used in the wine industry, is yet another way of clarifying juice. Instead of the solids settling out to the bottom of a tank by gravity (as has been a long standing and common practice), using the flotation process, the solids are agglomerated and rise to the surface of the tank or vessel by the action of gas bubbles. Flotation is primarily used in the production of white and rosé wines.
